Bambu Lab PET-CF Black
Features
• Extremely low hygroscopicity
• Excellent mechanical properties
High dimensional stability
• Excellent heat resistance
• Equipped with high-temperature reusable spools
• Diameter: 1.75mm +/- 0.03mm
Bambu PET-CF is a blend of tough PET and carbon fiber. The carbon fiber enhances stiffness and mechanical strength while still helping to maintain the low warpage and shrinkage of regular PET. Bambu PET-CF offers excellent heat resistance and a soft, luminous appearance. Its superior strength, heat resistance, dimensional stability, and low moisture absorption make Bambu PET-CF ideal for load-bearing structures or printed materials used in high-temperature and humid environments.
With low hygroscopicity, PET-CF exhibits minimal loss of strength and stiffness under saturated water absorption conditions, making it suitable for printing in high humidity environments.
Normal PA-CF
Bambu PET-CF
Loading weight: 1 kg
The test model has a span of 220 mm and a thickness of 3 mm under no-load conditions.
High dimensional stability
Due to the creep resistance and warping resistance of PET-CF, printed parts can achieve excellent matching accuracy.
Sample dimensions (length * width * height): 240 * 8 * 15 mm³
Filler density: 60%
Excellent heat resistance
• Sample dimensions (length * width * height): 95 * 10 * 4 mm³
• Test conditions: Place the samples in ovens at 70 °C and 150 °C for 0.5 hours respectively.
• PLA, as a crystalline material, only deforms significantly when the temperature exceeds its melting point (approximately 155°C).
